COSEL launches compact 2”x3” power supply series for medical applications

COSEL has extended its medial power offering with the new UMA series, the first two models being the 30W UMA30F and the 60W UMA60F.

Both feature a universal input range of 85 to 264VAC and comply with international safety standards. Designed for demanding medical applications, the UMA series is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement.

Based on a robust platform, the units’ design has been optimised to provide a suitable price/performance ratio for medical applications requiring a high quality power solution. The UMA series is available in up to five output voltages of 5, 12, 15, 24, and 48VDC.

The UMA series can be operated within a universal Input range of 85 to 264VAC, and has a typical efficiency up to 91% at high line.

Currently four single output voltages are available as standard for the UMA30F: 5V/3A, 12V/2.5A, 24V/1.3A and 48V/0.65A, and five for the UMA60F: 5V/6A, 12V/4.5A, 15V/3.5A, 24V/2.5A and 48V/1.25A. Output is factory adjusted to a fixed value, but in applications where output voltage adjustment is required an option ‘Y’ with potentiometer is available.

The UMA series includes inrush current limiting circuitry, overcurrent, and overvoltage protection. Exhibiting versatility and robustness, the power supplies can be operated in an environmental temperature range of -20 to +70 degrees centigrade. Depending on the final equipment assembly style and cooling conditions, a derating may apply.

With its medical focus, the UMA series’ input to output isolation complies with 2MOPP, its input to Frame Ground (FG) complies with 1MOPP, and output to FG with 1MOPP. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition. In the case of Body Floating applications where patient leakage current must be less than 100 µA, with its 75 µA figure the UMA series is well below that limit and so eminently suitable for such applications.

The UMA series meets the following agency approvals: ANSI/AAMI ES60601-1, EN60601-1 3rd, C-UL (equivalent to CAN/CSA-C22.2 No.60601-1), UL62368-1, EN62368-1, C-UL (equivalent to CAN/CSA-C22.2 No.62368-1) and complies with EN60335-1.

To accommodate application specific requirements, three options are available including adjustable output voltage (Y), terminal block (T), and for applications requiring additional safety the UMA30F and UMA60F are available with reinforced isolation in conformance with the IEC class II (E).

The UMA30F measures 50.8 x 21.7 x 76.2mm [2.0 x 0.85 x 3.0 inches] (W x H x D) and weighs 80g max. The UMA60F is just 2.5mm taller (24.2mm) and weighs 120g max.

The UMA series has a five-year warranty and conforms to the European RoHS and Low Voltage Directives.
